If a `do concurrent` loop is offloaded then there should be no CUDA data transfer in it. Update the semantic and lowering to take that into account. `AssignmentChecker` has to be put into a separate pass because the checkers in `SemanticsVisitor` cannot have the same `Enter/Leave` functions. The `DoForallChecker` already has `Eneter/Leave` functions for the `DoConstruct`.
